Alright, short but sweet!
I loved the way the music tempo lined up with the bobbing of the rings. However, it was a little difficult to tell which rings were which colour. A slightly larger difference in colour between the two racers might have been nice!
Also, although it is a two player game, I'm not sure how much you can call them a team - they don't interact with each other at all besides one of them maybe screwing the other over by boosting too much. Definitely fun though, and I wouldn't have minded playing on if the level was longer, but as the title says; more of a race than a teamgame!
